In August i will get the car dynoed again from the same place, it was 254hp at the flywheel as well, you can also see two big dips and how fuzzy the chart looks, not smooth but i know there was an air leak, could had caused that.

No, that is completely normal. Those dips are caused by the disa valves in the intake manifold. Healthy numbers - if you don’t plan on doing headers, a good intake and exhaust - and @cobramarty MILVs will give another 10whp+ on top of that.
